    Screening for proteinuria and hematuria is important in the prevention of chronic renal disease. In Malaysia to date no such attempt has been made to establish the prevalence of proteinuria and hematuria. A total of 45,149 primary school children from three districts in Kelantan were screened for proteinuria and hematuria. They were 23,289 boys and 21,860 girls. The prevalence of abnormal urinary sediments after third screening was 0.17% ie 0.07% were in boys and 0.10% were in girls. The commonest abnormality was proteinuria (0.12%), followed by hematuria (0.03%) and combination of proteinuria and hematuria (0.02%). Hematuria was more commonly seen in girls compared to boys while proteinuria was seen in almost equal proportion in boys and girls. Despite screening large number of children the prevalence of asymptomatic proteinuria and hematuria was far lower than in an earlier reported study. Furthermore the majority had mild abnormalities.

    BACKGROUND AND OBJECTIVES: Noninvasive urine screening for Chlamydia trachomatis infections offers a valuable public health tool, which could be of vast importance in chlamydial control programs. The authors evaluated a new DNA amplification method, ligase chain reaction (LCR).

    GOALS: The goal was to ascertain whether urine testing could be used as screening method to detect C. trachomatis infections in commercial sex workers, patients at sexually transmitted diseases clinic, and asymptomatic patients in Kuala Lumpur, Malaysia.

    METHODS: First-void urine specimens from 300 men and 300 women were tested by LCR, as well as by a commercially available enzyme immunoassay. The LCR assay amplifies specific sequences within the chlamydial plasmid with ligand-labeled probes, and the resultant amplicons are detected by an automated immunoassay. Specimens with discrepant results were confirmed by another LCR of the specimen that targeted the gene for the major outer membrane protein (OMP1).

    RESULTS: There were 31 LCR-positive male urine and 37 LCR-positive female urine specimens. The resolved sensitivity and specificity for the LCR of the male urine specimens were 100% and 99.6%, respectively, whereas for female urine specimens, the sensitivity and specificity were 100% and 98.5%, respectively. After resolution of discrepant test results by OMP1 LCR, the prevalence was 10% for men and 11% for women. The urine enzyme immunoassay was not useful in diagnosing C. trachomatis infections in either men or women, as the resolved sensitivities were 10% and 15.2%, respectively. The specificities were 99.6% for men and 98.9% for women.

    CONCLUSIONS: Testing first-void urine specimens by LCR is a highly sensitive and specific method to diagnose C. trachomatis infections in men and women, providing health care workers and public health officials with a new molecular amplification assay that uses noninvasive urine specimens for population-based screening purposes.

    Undernutrition and the consumption of poor diets are prevalent among elderly people in developing countries. Recognising the importance of the early identification of individuals at high nutritional risk, this study aimed to develop a simple tool for screening. A cross-sectional study was conducted on 11 randomly selected villages among the 62 in Mersing District, Malaysia. Undernutrition was assessed using body mass index, plasma albumin and haemoglobin on 285 subjects. Dietary inadequacy (a count of nutrients falling below two-thirds of the Recommended Dietary Allowances) was examined for 337 subjects. Logistic regression analysis was performed to identify significant predictors of undernutrition and dietary inadequacy from social and health factors, and to derive appropriate indices based on these predictions. The multivariate predictors of undernutrition were 'no joint disease', 'smoker', 'no hypertension', 'depended on others for economic resource', 'respiratory disease', 'perceived weight loss' and 'chewing difficulty', with a joint sensitivity of 56% and specificity of 84%. The equivalent predictors of dietary inadequacy were 'unable to take public transport', 'loss of appetite', 'chewing difficulty', 'no regular fruit intake' and 'regularly taking less than three meals per day', with a joint sensitivity of 77% and specificity of 47%. These predictions, with minor modification to simplify operational use, led to the production of a simple screening tool. The tool can be used by public health professionals or community workers or leaders as a simple and rapid instrument to screen individual at high risk of undernutrition and/or dietary inadequacy.

    OBJECTIVE: Dihydropyrimidine dehydrogenase (DPD) catalyzes the degradation of thymine, uracil, and the chemotherapeutic drug 5-Fluorouracil. In general reverse-phase high pressure liquid chromatography is the standard method for separating 5-[2-(14)C]Fluorouracil and 5-[2-(14)C]Fluoro-5,6-dihydrouracil. However, the use of 100% aqueous solution (as HPLC mobile phase) may collapse the C-18 bonded phase and result in a retention time shift. The aim of this study is to develop a rapid, reproducible, sensitive method for screening partial DPD deficiency in healthy volunteers.

    DESIGN AND METHODS: The activity of DPD was measured using 5-[2- (14)C]Fluorouracil (5-[2-(14)C]FUra) followed by separation of substrate and product 5-[2-(14)C]FUraH(2) with a 15 x 4.6 mm I.D., 5 microm particle size (d(p)) porous graphitic carbon (PGC) column (Hypercarb(R)) and HPLC with online detection of the radioactivity. This was standardized using the protein concentration of the cytosol (NanoOrange(R) Protein Quantitation).

    RESULTS: Complete baseline separation of 5-[2-(14)C]Fluorouracil (5-[2-(14)C]FUra) and 5-[2-(14)C]Fluoro-5,6-dihydrouracil (5-[2-(14)C]FUraH(2)) was achieved using a porous graphitic carbon (PGC) column. The detection limit for 5-[2-(14)C]FUraH(2) was 0.4 pmol.

    CONCLUSIONS: By using linear gradient separation (0.1% Trifluoroacetic acid [TFA] in water to 100% Methanol) protocols in concert with PGC columns (Hypercarb(R)), we have demonstrated that a PGC column has a distinct advantage over C-18 reverse phase columns in terms of column stability (pH 1-14). This method provides an improvement on the specific assay for DPD enzyme activity. It is rapid, reproducible and sensitive and can be used for routine screening for healthy and cancer patients for partial and profound DPD deficiency before treatment with 5- FUra.

    Body Mass Index (BMI) is the most established anthropometric indicator used for assessment of nutritional status. Other anthropometric indicators which are related closely to BMI are waist hip ratio (WHR) and waist circumference. In this paper, receiver operating characteristics (ROC) curves were constructed to assess the value of waist circumference and waist hip ratio as a screening measure for the need of weight management using BMI as the reference test. Sensitivity and specificity were calculated at several cut-offs. The areas under the ROC curve calculated by comparing waist circumference with BMI were high (0.70 - 0.86) while the areas calculated for WHR were low (0.46 - 0.67). Sensitivities of 0.745 and 0.800 were observed at cut-off points of waist circumference at 90cm and 80cm for males and females respectively, while the false positive rates were 0.233 for males and 0.250 for females. These cut-off points could be considered as a fair trade-off. Therefore it is concluded that waist circumference performed better than WHR as a screening test. It is indicative that waist circumference could be used as a tool in raising awareness of weight management in this population.

    A monoclonal antibody (MAb) based solid-phase blocking ELISA was developed for detection of antibodies to Nipah virus. The ELISA was designed to detect remaining antigens on the plate with anti-Nipah MAb conjugate after the reaction with sample serum, and enabled simple procedure, detection of neutralizing antibody to Nipah virus, and application of samples from different animal species. Forty of 200 swine reference sera examined were positive by the ELISA, of which thirty seven were found positive by serum neutralization test. Sera from a total of 131 fruit bats captured in Malaysia were also tested and all found negative by the both tests. It is considered that the solid-phase blocking ELISA can be used as a screening test for Nipah virus infection followed by the serum neutralization test as confirmatory test.

    INTRODUCTION: This article reviews published literature on the usefulness of population-based urinary screening in the Asian paediatric population.

    METHODS: Articles were found in the Medline database using the key words "paediatrics", "urine screening", "proteinuria", "haematuria" and "population". The Asian countries which had carried out population-based urinary screening of the paediatric population included Taiwan, Japan and Korea. One study was found on urinary screening in a select population in Malaysia. Preliminary results of the urinary screening of school children in Singapore are presented and compared with the results found in the above-mentioned countries.

    RESULTS: Overall, the proportion of children found to have urinary abnormalities ranged from less than 0.1% of the population screened to almost 50% of a select cohort referred from the screening programmes for the evaluation of urinary abnormalities. In the pilot Singapore school screening programme, the prevalence of clinically significant proteinuria was 1.25 per 1000 children screened. Multivariate analysis showed that low body weight was associated with a 1.8-fold greater risk for proteinuria. The major cause of haematuria and proteinuria in those studies where renal biopsies were performed was glomerulonephritis. The Taiwanese experience also showed a reduction in the incidence of end-stage renal failure diagnosed in children after the onset of urine screening.

    CONCLUSION: These studies showed that urinary screening programmes in school children allow the early detection of disease. The cost-benefit ratio for specific populations should be determined before the implementation of such programmes.

    BACKGROUND: The incidence of postsurgical venous thromboembolism is thought to be low in Asian ethnic populations.

    OBJECTIVE: We studied the incidence of deep-vein thrombosis (DVT) in Asian patients undergoing major orthopedic surgery of the lower limbs.

    PATIENTS/METHODS: We performed a prospective epidemiological study in 19 centers across Asia (China, Indonesia, South Korea, Malaysia, Philippines, Taiwan, and Thailand) in patients undergoing elective total hip replacement (THR), total knee replacement (TKR) or hip fracture surgery (HFS) without pharmacological thromboprophylaxis. The primary endpoint was the rate of DVT of the lower limbs documented objectively with bilateral ascending venography performed 6-10 days after surgery using a standardized technique and evaluated by a central adjudication committee unaware of local interpretation.

    RESULTS: Overall, of 837 Asian patients screened for this survey, 407 (48.6%, aged 20-99 years) undergoing THR (n = 175), TKR (n = 136) or HFS (n = 96) were recruited in 19 centers. DVT was diagnosed in 121 of 295 evaluable patients [41.0%, (95% confidence interval (CI): 35.4-46.7)]. Proximal DVT was found in 30 patients [10.2% (7.0-14.2)]. Total DVT and proximal DVT rates were highest in TKR patients (58.1% and 17.1%, respectively), followed by HFS patients (42.0% and 7.2%, respectively), then THR patients (25.6% and 5.8%, respectively). DVT was more frequent in female patients aged at least 65 years. Pulmonary embolism was clinically suspected in 10 of 407 patients (2.5%) and objectively confirmed in two (0.5%).

    CONCLUSIONS: The rate of venographic thrombosis in the absence of thromboprophylaxis after major joint surgery in Asian patients is similar to that previously reported in patients in Western countries.

    The aim of this study was to screen and identify the types of thalassemia among blood donors at the Hospital Universiti Sains Malaysia (HUSM). Thalassemia screening was performed by hemoglobin electrophoresis. A total number of 80 blood samples were obtained from donors at the Transfusion Medicine Unit, HUSM. The ethnic origins of the donors were Malays (n=73, 91.3%) and non-Malays (n=7, 8.75%). Males comprised 88.1% of the donors. Thalassemia was detected in 16.25% (n=13) of the blood donors. Of those with thalassemia, 46.2% (6/13) were anemic. Microcytosis and hypochromia were detected in 84.6% (n=l1) and 84.6% (n=l1) of these donors, respectively. The types of thalassemias detected were Hb E, 11.25% (n=9/80) and beta thalassemia trait, 5% (n=4/80). Among the thalassemias detected, the Hb E hemoglobinopathy was comprised of Hb E/ alpha-thalassemia (38.5%: n=5), Hb E /beta-thalassemia (23.1%: n=3), Hb E trait (7.6%: n=1) and beta-thalassemia (30.8%: n=4). In conclusion, screening for thalassemia trait should be included as part of a standard blood testing before blood donation. Further studies are required to look at the effects of donated thalassemic blood.

    OBJECTIVES: To assess whether or not opportunistic oral cancer screening by dentists to detect pre-malignant or early cancer lesions is feasible. The objective was to analyse the patterns of dental attendance of a national representative sample over a period of 10 years to ascertain whether individuals at high-risk of oral cancer would be accessible for opportunistic oral cancer screening.

    METHODS: Secondary analysis of data extracted from the British Household Panel Survey, a national longitudinal survey (n=5547). Analysis to ascertain whether patterns of attendance for dental check-ups for a period of 10 years (1991-2001) were associated with risk factors for oral cancer such as age, sex, education, social class, smoking status and smoking intensity.

    RESULTS: Males, aged over 40 years, less educated manual workers and smokers were significantly less likely to attend for dental check-ups compared with females and younger, higher educated, higher socio-economic class non-smokers (p < 0.05). Throughout the 10-year period, young people, more than older people, had progressively lower odds ratios of attending. Those with more education used dental services more. Heavy smokers were infrequent attendees.

    CONCLUSIONS: This study suggests that opportunistic oral cancer screening by dentists is not feasible to include high-risk groups as they are not regular attendees over 10 years. Those who would be screened would be the low-risk groups. However, dentists should continue screening all patients as oral precancers are also found in regular attendees. More should be done to encourage the high-risk groups to visit their dentists.

    INTRODUCTION: Breast cancer is the commonest female cancer in Singapore. It is steadily rising with an incidence of 53.1 cases per 100,000 persons per year among women. Screening for detection of early lesions which are highly curable helps to reduce mortality.
    METHODS: Over three afternoon sessions in December 2003, 224 female patients aged 40-65 years, participated in interviews conducted by the National Healthcare Group Polyclinics, Singapore. The survey sought information on mammographic screening history, the time interval since the previous mammographic screening, and the reasons for not going for the screening.
    RESULTS: The survey found that only 26.4 percent (28 out of 106) among those aged 40 to 49 years had mammographic screening done within the past one year, and 43.2 percent (51 out of 118) among those aged 50 to 65 years had screening done within the last two years. Chinese women were twice more likely than Malay women to have a mammogram done. The commonest reasons for not wanting to have mammographic screening among women who did not have a mammogram done or had mammogram done more than two years ago, were lack of time (42.5 percent), fear of pain during the procedure (26.9 percent), and the belief that cancer would not happen to them (24.6 percent).
    CONCLUSION: Despite publicity on breast cancer being the commonest cancer among women in Singapore and cure being possible if the malignancy was detected early, close to half of the women aged 40-65 years old who attended the National Healthcare Group Polyclinics did not have mammographic screening done. One-quarter of the women who did not have mammogram screening did not do so as they did not think cancer would happen to them.

    Background: The best method of screening for gestational diabetes (GDM) remains unsettled. The 50-g glucose challenge test (GCT) is used in a two-stage screening process but its best threshold value can vary according to population.

    Aims: To evaluate the role of risk factors in conjunction with GCT and to determine an appropriate threshold for the one-hour venous plasma glucose with the GCT.

    Method: In a prospective study, 1600 women at antenatal booking without a history of diabetes mellitus or GDM filled a form on risk factors before GCT. Women who had GCT >or= 7.2 mmol/L underwent the 75-g oral glucose tolerance test (OGTT). GDM was diagnosed according to WHO (1999) criteria.

    Result: Thirty-five per cent had GCT >or= 7.2 mmol/L, 32.6% underwent OGTT and 34.5% of OGTT confirmed GDM. The GDM rate in our population was at least 11.4%. Examination of the receiver operator characteristic curve suggested that the best threshold value for the GCT in our population was >or= 7.6 mmol/L. Multivariable logistic regression demonstrated that only GCT >or= 7.6 mmol/L was an independent predictor for GDM (adjusted odds ratio 3.7: P < 0.001). After GCT, maternal age and anthropometry, OGTT during the third trimester, family history, obstetric history and glycosuria were not independent predictors of GDM.

    Conclusions: Risk factors were not independent predictors of GDM in women with GCT >or= 7.2 mmol/L. GCT threshold value >or= 7.6 mmol is appropriate for the Malaysian population at high risk of GDM.

    The objective of this study was to identify haematological parameters useful in screening for iron deficiency among blood donors. Iron deficiency is a common complication of blood donation and often goes unrecognized until anaemia develops. Biochemical markers such as soluble transferrin receptor (TfR), ferritin and log(TfR/F) have been proposed as more valid indicators of body iron status. Red blood cell (RBC) parameters are, however, more easily measured and have also been proposed as indicators of iron depletion. We measured ferritin and TfR in 192 blood donors together with RBC analysis, performed on two haematology analysers. Thirteen donors had parameters suggestive of haemoglobinopathy and were excluded from further analysis. Overall, 10% (18/179) of the remaining donors had iron deficiency, as defined by log(TfR/F) exceeding the 95th percentile of the value in the population of first-time donors. Using receiver operating characteristic analysis, the sensitivity of ferritin was 100%, with a specificity of 90% at a cut-off of 15 mug L(-1). The sensitivity and specificity of RBC-Y at a cut-off of 152 for detecting iron deficiency were 81 and 89%, respectively. Haemoglobin content of reticulocytes, meanwhile, showed sensitivity of 69% and specificity of 93% when a cut-off of 28 pg was used. Both measures compare favourably with haemoglobin which only showed a sensitivity of 50%, although specificity was 91% at a cut-off value of 125 g L(-1). The parameter RBC-Y can be useful as a screening measure for iron deficiency in blood donors.

    Cervical cancer remains one of the leading causes of cancers in women from Indonesia, Malaysia, the Philippines, Thailand and Vietnam. High-risk human papillomavirus (HPV) types, particularly HPV-16 and 18, are consistently identified in cervical cancer cases regardless of geographical region. Factors that have been identified to increase the likelihood of HPV exposure or subsequent development of cervical cancer include young age at first intercourse, high parity and multiple sexual partners. Cervical cancer screening programs in these countries include Pap smears, single visit approach utilizing visual inspection with acetic acid followed by cryotherapy, as well as screening with colposcopy. Uptake of screening remains low in all regions and is further compounded by the lack of basic knowledge women have regarding screening as an opportunity for the prevention of cervical cancer. Prophylactic HPV vaccination with the quadrivalent vaccine has already been approved for use in Malaysia, the Philippines and Thailand, while the bivalent vaccine has also been approved in the Philippines. However, there has been no national or government vaccination policy implemented in any of these countries.

    AIMS: To evaluate Fourier transform infrared (FTIR) spectroscopy as new tool for screening of cervical cancer in comparison with cervical cytology.

    METHODS: A total of 800 cervical scrapings were taken by cytobrush and placed in ThinPrep medium. The samples were dried over infrared transparent matrix. Beams of infrared light were directed at the dried samples at frequency of 4000 to 400 cm(-1). The absorption data were produced using a Spectrum BX II FTIR spectrometer. Data were compared with the reference absorption data of known samples using FTIR spectroscopy software. FTIR spectroscopy was compared with cytology (gold standard).

    RESULTS: FTIR spectroscopy could differentiate normal from abnormal cervical cells in the samples examined. The sensitivity was 85%, specificity 91%, positive predictive value 19.5% and negative predictive value of 99.5%.

    CONCLUSION: This study suggests that FTIR spectroscopy could be used as an alternative method for screening for cervical cancer.

    Breast cancer is the leading cause of cancer deaths in Malaysian women, and the use of breast self-examination (BSE), clinical breast examination (CBE) and mammography remain low in Malaysia. Therefore, there is a need to develop a valid and reliable tool to measure the beliefs that influence breast cancer screening practices. The Champion's Health Belief Model Scale (CHBMS) is a valid and reliable tool to measure beliefs about breast cancer and screening methods in the Western culture. The purpose of this study was to translate the use of CHBMS into the Malaysian context and validate the scale among Malaysian women.

    Despite being an emergent major public health problem, little research has been done on domestic violence from the perspectives of early detection and prevention. Thus, this cross-sectional study was conducted to identify domestic violence among female adult patients attending health centers at the primary care level and to determine the relationship between social correlates of adult patients and domestic violence screening and subsequent help/health-seeking behavior if abused. Face-to-face interviews were conducted with 710 female adult patients from 8 health centers in Selangor who matched the inclusion criteria and consented to participate in the study, using a structured questionnaire that included adaptation of a validated 8-item Women Abuse Screening Tool (WAST). Statistical tests showed significant differences in ethnicity, income, and education between those screened positive and those screened negative for domestic violence. Of the participants, 92.4% reported that during consultations, doctors had never asked them whether they were abused by their husband/partner. Yet, 67.3% said they would voluntarily tell the doctor if they were abused by their husband/partner. The findings indicate that primary care has an important role in identifying domestic violence by applying the WAST screening tool, or an appropriate adaptation, with women patients during routine visits to the various health centers. Such assessment for abuse could be secondary prevention for the abused women, but more important, it will serve as primary prevention for nonabused women. This approach not only will complement the existing 1-stop crisis center policy by the Ministry of Health that copes with crisis intervention but also will spearhead efforts toward prevention of domestic violence in Malaysia.

    INTRODUCTION: An important risk factor for developing breast cancer is a positive family history of breast cancer. In Malaysia, there is no population-based breast screening programme, but the clinical practice guidelines suggest increased surveillance for those with a positive family history ie mammography for those 40 years old and above, breast self-examination and clinical breast examination yearly.
    OBJECTIVE: To determine if women with a family history of breast cancer present with earlier stages of disease.
    METHODOLOGY: From Jan 2001 to Dec 2006, 1553 women with breast cancer presenting to the University Malaya, where family history was recorded, were eligible for this study. Women with a first or second degree relative with breast cancer were compared with those who have no family history with regard to their race, age, stage, size and duration of symptoms. The Chi Square test of significance was used for analysis.
    RESULTS: Out of 1553 patients, 252 (16.2%) were found to have a relative with breast cancer out of which 174 (11.2%) had at least one affected first degree relative. There were no significant difference in the incidence of positive family history between the Malays, Chinese and Indians. 20% below the age of 40 years old had a positive family history compared with 12.6% in women with no family history. (p<0.05). There was no significant difference in stage at diagnosis between those with and without family history, ie 24.2% late stages (Stage 3 and 4) in the group with no family history compared with 21.8% in the group with family history. (p>0.05). The mean size in the group with no family history was 4.4 cm compared to 4.1 cm in the group with family history. There was a significant difference in screen-detected cancers in the women with family history, 10.7% compared with 5.1% of screen-detected cancers in the group without a family history. However there was no difference in the duration of symptoms between the 2 groups--25.8% in the women without a family history presented after 1 year of symptoms compared with 22.4% in the group with a family history (p>0.05).
    CONCLUSION: Having a family history of breast cancer does not appear to have much impact on the health-seeking behavior of women. Even though there were more screen detected cancers, these comprised only 10% of the group with family history. Public education should target women at risk ie with family history to encourage these women to present earlier and to undergo screening for breast cancer.

    A cross-sectional study was conducted at the main hospitals in Sana'a, Yemen to determine the attitude and practice of Yemen female doctors on mammography screening. Study subjects were all female doctors who were on duty during the questionnaire distribution. Those who agreed to participate were given the questionnaire to complete. Descriptive statistics were used to analyse socio-demographic variables and variables related to general health. Participants in this study were 105 female doctors with mean age of 32.1 years (SD = 7.17). Thirty-four respondents (36.6%) did not send asymptomatic women for mammography screening. The reasons were because of high cost (58.0%, n= 25), availability of other methods (23.3%, n= 10), instrument not available (11.6%, n= 5) and high risk of radiation (7.0%, n= 3). Twenty-five participants (26.9%) sent patients on regular basis if there was a family or personal history of breast cancer. Twenty-three participants (24.7%) sent the patients for mammogram screening every year regardless of the patients'history or symptoms. Although most doctors (36.5%) do not refer patients for mammography screening, seventy-seven (74.0%) indicated that they would refer patients for mammography screening on personal request by the patients. This study showed a low percentage of doctors who referred patients for routine mammography. The major reason given was the high cost of the procedure.
